 By the way, in a meandering prevention conveyor belt, a belt main body is wound between a main driving pulley and a driven pulley, and a guide body disposed on the back surface of the belt main body is formed on a peripheral surface of the main driving pulley and the driven pulley. By fitting in the groove, it prevents the belt body from meandering when running, and it is necessary to accurately fit the guide body and the guide groove, but setting of the meandering prevention conveyor belt It is said that the guide body and the guide groove are not fitted correctly due to mistakes (setting of the distance between the drive pulley and the driven pulley, etc.) and the progress of use (looseness due to stretching of the belt body, etc.). Things are happening.

When the guide body and the guide groove are not accurately fitted together due to a setting error or the progress of use, the guide body passes over the side wall of the guide groove and the driving pulley or the driven pulley is driven. If the belt body is stretched by the thickness of the guide body, and if the belt body is mesh-shaped or plain weave, the above-mentioned stretching will cause meshing or meshing. Distortion will occur in the weave, and contraction in the width direction of the belt body will occur due to the elongation generated in the longitudinal direction of the belt body, so that the fitting between the guide body and the guide groove becomes even more inaccurate. However, the running of the belt body is not stable, and it becomes impossible to accurately carry articles and sort work by the meandering prevention conveyor belt, and the guideability and durability of the guide body are impaired. It was something that would be broken.

As described above, in the present embodiment, the pair of guide members 11a and 11b forming the guide body guiding device in the meandering prevention conveyor belt face each other and form a pair of rollers 14 (a pair of rollers 14). Of which the belt main body 1 and the guide body 4 travel smoothly with respect to the pair of guide members 11a and 11b, and the belt main body of the meandering preventive conveyor belt is formed. 1 is stable, the articles are accurately conveyed and sorted by the meandering-preventing conveyor belt, and the guide body 4 is prevented from being worn, so that the guide body 4 is improved in guide property and durability.

Further, the peripheral surface 15 and the peripheral surface side portion 16 of each of the rollers 14 constituting the pair of guide members 11 a and 11 b and the peripheral surface 22 of the belt pressing member 17 for pressing the surface 3 of the belt body 1 are By covering with a plastic resin with excellent wear resistance such as nylon resin or fluororesin, friction with the belt body 1 and friction with the guide body 4 are reduced, and the running of the belt body 1 and the guide body 4 is reduced. It will be done more smoothly.

Next, the guide device of the guide body in the meandering prevention conveyor belt shown in FIGS. 10, 11, 12, and 13 is a third embodiment which is a modification of the second embodiment. In this embodiment, a pair of guide members 11a and 11b forming a guide device for a guide body in a meandering-preventive conveyor belt are rollers 14 which face each other and are used in another embodiment. Therefore, the pair of rollers 14 are arranged such that their rotating surfaces are parallel to each other, and the circumferential surface side portions 16 of each of the rollers 14 facing each other are arranged on the back surface 2 of the belt body 1. It is used as a pair of guide surfaces 12a and 12b that come into contact with the inner side surface 5a and the outer side surface 5b of the body 4, respectively. In the present embodiment, a pair of rollers 14 that face each other are used. Therefore, a case where a pair of guide members 11a and 11b are formed is shown.

The rollers 14 that are arranged so that their rotation surfaces are parallel to each other and that face each other are attached to the frame body 20 (see FIG. 12) of the meandering-preventing conveyor belt, 1. The guide member 4 is pivotally supported by a mounting member 18 located on the side of 1 and is above the rollers 14 which face each other and are engaged when the guide body 4 is engaged with the pair of guide members 11a and 11b. In order to maintain the combined state, the front surface 3 of the belt main body 1 is pressed against the pair of guide members 11a and 11b located on the back surface 2 side of the belt main body 1 and is rotated R in the traveling direction F of the belt main body 1. Two belt pressing members 17 are provided, and the belt pressing member 17 is axially supported so that its position can be adjusted in the up-down direction Y with respect to the mounting member 18.

In the case of the present embodiment, a pair of rollers 14 forming a pair of guide members 11 a and 11 b, which face each other, and two belt pressing members 17 which press the surface 3 of the belt body 1, The belt main body 1 is arranged so as to sandwich the belt main body 1, and a pair of rollers 14 facing each other and the front surface 3 of the belt main body 1 are pressed along the traveling direction F of the back surface 2 and the front surface 3 of the belt main body 1. Since the two belt pressing members 17 rotate R, the belt main body 1 travels more smoothly.

Further, at this time, the guide body 4 disposed on the back surface 2 of the belt body 1 is securely engaged with the pair of guide members 11a and 11b constituted by the pair of rollers 14 facing each other. As a result, the guide body 4 is accurately guided into the guide groove 9, the traveling of the meandering prevention conveyor belt is stabilized, and the conveyance and sorting work of the articles by the meandering prevention conveyor belt is performed more accurately. The wear of the guide body 4 is prevented, and the guide properties and durability of the guide body 4 are improved.

A ball bearing is considered as the roller 14 and the belt pressing member 17 used in the second and third embodiments, and by using a standard off-the-shelf ball bearing, It is possible to form a guide body guiding device for a meandering prevention conveyor belt at a very low cost.

In this embodiment, the guide body guiding device in the meandering prevention conveyor belt of the present invention is arranged on the driving pulley 6 side, but it is arranged on the driven pulley 7 side. Since the same is true for the case, the description thereof will be omitted.
